// http://code.google.com/p/cityhash/
|
||||
//
|
||||
// This file provides a few functions for hashing strings. All of them are
|
||||
// high-quality functions in the sense that they pass standard tests such
|
||||
// as Austin Appleby's SMHasher. They are also fast.
|
||||
//
|
||||
// For 64-bit x86 code, on short strings, we don't know of anything faster than
|
||||
// CityHash64 that is of comparable quality. We believe our nearest competitor
|
||||
// is Murmur3. For 64-bit x86 code, CityHash64 is an excellent choice for hash
|
||||
// tables and most other hashing (excluding cryptography).
|
||||
//
|
||||
// For 64-bit x86 code, on long strings, the picture is more complicated.
|
||||
// On many recent Intel CPUs, such as Nehalem, Westmere, Sandy Bridge, etc.,
|
||||
// CityHashCrc128 appears to be faster than all competitors of comparable
|
||||
// quality. CityHash128 is also good but not quite as fast. We believe our
|
||||
// nearest competitor is Bob Jenkins' Spooky. We don't have great data for
|
||||
// other 64-bit CPUs, but for long strings we know that Spooky is slightly
|
||||
// faster than CityHash on some relatively recent AMD x86-64 CPUs, for example.
|
||||
// Note that CityHashCrc128 is declared in citycrc.h.
|
||||
//
|
||||
// For 32-bit x86 code, we don't know of anything faster than CityHash32 that
|
||||
// is of comparable quality. We believe our nearest competitor is Murmur3A.
|
||||
// (On 64-bit CPUs, it is typically faster to use the other CityHash variants.)
|
||||
//
|
||||
// Functions in the CityHash family are not suitable for cryptography.
|
||||
//
|
||||
// Please see CityHash's README file for more details on our performance
|
||||
// measurements and so on.
|
||||
//
|
||||
// WARNING: This code has been only lightly tested on big-endian platforms!
|
||||
// It is known to work well on little-endian platforms that have a small penalty
|
||||
// for unaligned reads, such as current Intel and AMD moderate-to-high-end CPUs.
|
||||
// It should work on all 32-bit and 64-bit platforms that allow unaligned reads;
|
||||
// bug reports are welcome.
|
||||
//
|
||||
// By the way, for some hash functions, given strings a and b, the hash
|
||||
// of a+b is easily derived from the hashes of a and b. This property
|
||||
// doesn't hold for any hash functions in this file.
